You've always had a love hate relationship with your stepsis, you grew up together but noticed she started being more distant and bitchy as she got older and hotter. She didn't have much time for brother sister bonding anymore and you've finally decided to convince her to try something you've always fantasized about doing...fucking your hot stepsis. You sneak into her bedroom while she is napping and try to convince her that its all innocent curiosity. Even though she is a little bossy and insists you leave, she finally caves before rushing you to cum as she hears mom and dad return home!
